DEVICE FOR CLEANING THE FLATS IN GARDING-ENGINES.

I (1H- u'llom it may concern.

Be it known that 1, human Dnarnn, a subject of the King of (treatBritain, and resident of liorlw. in the county of Lancaster, jlngland.have invented a certain new and useful lin worcnient in Devices forCleaning the Fhits in Carding-Engim-s, of which the followingdcscription. having reference to the :m-onipanying sheets of drawin is as 'icciliration.

li [y invention relates to devices for use in removing the fibers, dirtand other waste or ohje'ctionabhmatter which accumulate between thepins, teeth or wires of the clothing fixed upon the flats in cardingengines. Usually these cleaning operations are 15erformed by rotarybrushes, combs or other devices covered with suitable material, suchbrushes or the like moving or operating in the same direction or inalinemcnt with the path of motion of said flats. and it is found thatthe waste 01' objectionable matter is not thereby entirely removed, butis to some extent pressed firmly upon the clothing between the pins sothat the lower portions of the latter or those parts thereof inproximity to the foundation in which they are place become covered orsurrounded. with substances held firmly in position. My presentinvention consists in the use or employment of means,

consisting of rotary brushes, which aretravarsed across thei'nachme-orlengthwise the liats instead of as licreinhefore descrihoth,

this traversing of said. cleaning brushes lieing performedautomatically, and with the brushes hai ing thciraxes in alinement withthe path of motion ofthe flats, or at an a)- propriate angle theretoother than a ri ht angle.

Tn order that my said invention may be readily understood. 1 havehereunto appended sheets of drawings illustrative then-oi, to whi h, byfigures and letters, relcrenre is made in the following description.

In the accompanying sheets of drawings, a indicates the main cylinder ofthe carding engine, and 7) a portion of the revolving flats from the.clothing of which it is desired to remove refuse. As will be wellunderstood. the flats 'bpass over the rollersc, c rand other guidingparts into proximity to or contact with the main 0 linder a, anditis'during the passage of tlioflnts over the cylinder fa that they becomecharged .iwith dirt, or waste. f 9

In carrying my invention into effect, I make use of a. brush or brushes(lwhich or are carried by a plate or bearings d such hearings fittingover projecting Apar'ts or pins 0 thitending from a plate yfiXEdOIconnected to the sleeve 0?, as by the extensions a, fulcrum pin e", andpinorholt je'". This sleeve '6 is mounted to slide upon a tube c withinwhich rotates a compound -or (low hle acting screw not well, known formhav ing a. fork g fitting tl-IGIBOVBI thQ connection between the fork-g:and thelsleeye a? hein such that said sleeyennd thestuhoi F may heturned around the screw? from the backward and forward across the facesof the flats upon which the two wheels or brushes (1 rotate as saidflats over or through the machine. The brushes (I may rest a ion thellatsby gravity or may he supported so that they do not press firmlyupon said flats but the clothing thereof merely passes through theclothing of the iiats I) so that they are rotated thereby. To supportsaid brushes and the parts carrying them, l

mount upon the tube c an adpistahle collar m provit ed with a projectingpart n i which comes into contact with a part of the bean ing 0 for thescrew pathos this projecting part it supports the weightof the extension5 e and parts carried therelrv. When moving the brushes 4 into theiosition shown in brokenlmes by 1 1g. 1 either the collar 11/ may beadjusted for the part a to again come into contact with another partolthe- Q bearing a or i magemake use of a separate sto rpiccei'or thispurpose.

he screw: 1/ is rotated in any suitable manor as by the pulley sopeiated.from the pulley a on the main shaft x by the ro'rd or 3 band 8.

The rollers or brushes (iJUIPCOYL'I'Ol with earda'lothing or similarnzaterial and the leading vwheel in each dirertion of trau-rse acrossthe flats I) has the wire portions of such clothing extending in snclrdirection as not to act as a cleaner for the flats!) but the clot hingon the other or following roller is arranged of the opposite hand orinthe oppo-.

site direction so that it lifts the waste and other refuse from theinterstices intervening between thewire of the card clothing: The platorl s readily reri'iovable from the pro electing parts 6, said plate r]-carrying the p rushes'or rollers d, and by the axes-of said rollers (Jnot descending below the horizontal plane or below their position inalinelire-fit with the axis of the screw y. these parts may merely restin position without the addition of extra nuts or fixingparts.

The brushes d may simply travel back ward and forward across the machineor lengthwise the flats, both of them rotating in contact with saidflats, or I may make use of means whereby the roller or brush which Q50is not performing its functions as a cleaner is rtiised out 'of contactwith the flats. This maybe efl'ected in any suitable manner. as bythee'mp'loynlent 'of'a rolling weight 11 inounted on or inthe'" late ortrough d, a

fifi'jprojeoting part as t at shown in dotted position projects throughthe slot r e. r

lines in Fig. 5 being mounted on each side of the machine with which aprojection r/ of the plate (1 comes into contact, thus at or near theend of the traverse of the brushes :1 in. one direction the contact ofthese parts will oscillate the bearing (1 and press the roller or brush(I which will during the out traverse be the cleaning hrusln intocontact with the clothing on the liats. while when this next traverse ofthe brushes is completed the other projecting part p on the other sideof the machine depresses said bearing (1 so that the other brush is thenpressed into contact with the that clothing to perform the cleaningoperations during the succeeding traverse.

To enable the brushes (1 to rise and pas over any obstruction they mayencounter i may provide the hearings or supports r, with a spring 1/which allows same to s\\i\ el on the pin. said support being manuallyheld in position by the tixed slip 1/, or other suit able means may beused for this purpose.

1 have hereinbetore described the employ ment of two brushes whichperform the cleaning operations alternately. but i mav employ one singlebrush as shown by Fig such brush efl'ecting the cleaning of the flatsinone direction but rotating idly in the op posite direction.

. I prefer to have taie cleaning device travarsed in a directionapproximately at right angles to the travel of the flats with the axisof the brush in alinement withsaid path of travel of the flats: however1 may if desired arrange same to travel thcreovei' obliquely or at anysuitable angle to this di" re tion.

in Figs. 5 and 9 l have shown a weighting device used in connection withmy invention. The sleeve c" tits over the sleeve w somewhat in themanner hereinbefore described. but

said sleeve is provided with projecting part:

c which form a support or bearings for a cross pin Ii nniunted on acurved part /i which spans a centrally disposed rib This curved part iiis provided with an we tending handle 11* the outer end Ii of which ispreferably larger than the other portions and is weighted with lead orthe like in order to' perform the dual otlice of a handle and weight.The brushes (I are carried by l-earings (l swiveling on a pin r attachedto the curved part 7;. When desired for an purpose the operator mayreadily raise said brushes 1/ out of contaet with the Hats l) b simplyturning the curved part ii on the inlerum pin- II. The weighted handleii" when the parts are in their normal position. presses the brushes 1)with sufiieicnt force into the card clothing on said flats Ii.

Instead of employing the brush or brushes acting as a cleareror elearersin onedireetiim only. i may employ a single brush which each side-of thecarding engine is rever. ed in direction so that it is capable of act'-g as vying hmn'ings for said brnshegs, and means for autaniatimillytraversing saldtlever arms and hearings from one side of thalnuvhine tothe utla-r and antnmatically traversing said la-arings in tho nppnsitcdirection.
